That was my first reaction when I read that Cisco Systems (NASDAQ:CSCO) was buying WebEx Communications (NASDAQ:WEBX) for $3.2 billion in cash.

Of course, that's not really fair. I was living and working in Silicon Valley during the heady days of the dot-com bubble. My instincts are hypersensitive when it comes to big-money tech deals, many of which were engineered by Cisco at the height of the madness.

How is WebEx different? Turns out it may not be different -- if you believe the numbers, that is:






Return on Assets





Return on Equity





Return on Capital

Notice the steady decline in performance. My guess is that's due to an increasing number of competitors in Web audio and video conferencing -- a market that WebEx all but pioneered at its founding in 1995.

Then there's the valuation. At $57 a share, Cisco values WebEx at 34 times this year's normalized earnings, or double its long-term growth projected growth rate of 17%. That's an impressive premium.

Yet there are two reasons why "CisEx" makes sense to me:

  1. WebEx is still far and away the leader in Web conferencing, commanding more than 67% of its market, according to Forrester Research.
  2. Cisco hopes to be leader in "Unified Communications," which, as I see it, means CEO John Chambers hopes to remake Cisco as the AT&T (NYSE:T) of data delivery. Being the leader in Web conferencing fits with that strategy.

So, with WebEx's dominance and Cisco's long-term strategy, maybe the premium for WebEx is justified. But even if it is, history reminds us to be cautious. Cisco still has plenty of competitors in Juniper (NASDAQ:JNPR) and Avaya (NYSE:AV), and its acquire-everything-we-need strategy failed investors once before, under the same CEO. What's different this time?
